OpenStreetMap/Nominatim routinely fails to work with simple bog-standard addresses around here, a major metropolitan area in the US. The reason, I believe, is that the city portion of addresses in this area often doesn't match the actual boundaries: locations well outside of the named city or town still have that in their address. Addresses are hard. And they don't necessarily line up as nicely with the data needed to make a map as you might think. And this is just for the "easy" stuff, really.
